BCM5665中文资料博通数据手册PDF规格书

High-Density and Line Rate Performance

The BCM5665 network switch is the most advanced multi-layer scalable, single-chip solution for high density 48 x 10/100 Mbps ports and 4 x 10/100/1000 Mbps Ethernet uplinks at aggregate line rate of 28 Mpps performance.

Ultra-Scalability

An integrated 10 Gbps XAUI HiGig port allows the BCM5665 to scale with other StrataXGS family switches. Multiple units can be networked for stackable or modular switch configuration in a system providing up to providing up to hundreds of Fast Ethernet, Gigabit Ethernet and 10 Gigabit Ethernet ports. The 10 Gbps HiGig Expansion port supports all key switch features, such as explicit priority, port trunking, mirroring and VC label swap functions, transparently across switch elements.
